Abstract
A standard potential used for reading is set flexibly according to the state of a storage device. A data memory cell group stores data. A reference memory cell group stores a plurality of reference potentials. A standard potential generating section selects a prescribed number of reference potentials from among the plurality of reference potentials stored in the reference memory cell group and generates the standard potential. A reference potential selection control section controls the selection by the standard potential generating section according to prescribed conditions. A sense amplifier amplifies data read out from the data memory cell group, by using the standard potential as a standard.
